[0007] First, the present invention will be described in general terms. A media mounting device according to a first aspect of the present invention for solving the above problems is a media mounting device capable of stacking a plurality of media discharged from a discharge section of a processing device, wherein the device comprises a plurality of support sections in a width direction intersecting the discharge direction of the media, which support the media discharged from the discharge section from below in the direction of gravity with a support surface, and the support sections alternately consist of a first support section and a second support section positioned lower in the direction of gravity than the first support section when viewed from the width direction, and the first support section is provided with a bridging member that bridges the lower side of the discharge section in the direction of gravity and the support surface of the first support section.
[0008] According to this embodiment, the first support section is provided with a bridging member that bridges the lower side of the discharge section in the direction of gravity and the support surface of the first support section. This prevents the leading edge of the discharged medium from sagging between the discharge section and the support surface, preventing the discharged medium from reaching the support surface, and also prevents the leading edge of the medium from getting caught in the discharge path between the discharge section and the support section. Therefore, the medium discharged from the processing device can be loaded appropriately. Furthermore, since the support section has a first support section and a second support section alternately in the width direction, the medium moving when viewed from the discharge direction can be made into a wavy shape, and the leading edge in the discharge direction from sagging and getting caught on the support surface or already placed medium can also be prevented.
[0009] In the medium placement device according to the second aspect of the present invention, in the first aspect, the support portion and the bridging member extend in the discharge direction and are inclined so as to be lower in the gravitational direction from the upstream side to the downstream side in the discharge direction.
[0010] According to this aspect, the support portion and the bridging member extend in the discharge direction and are inclined so as to be lower in the gravitational direction from the upstream side to the downstream side in the discharge direction. Therefore, the medium can be moved using gravity, and the medium can be efficiently moved without using power or the like.
[0011] In the medium placement device according to the third aspect of the present invention, in the second aspect, the bridging member includes a first bridging portion extending in the discharge direction from the first support portion, a second bridging portion provided on both sides of the first support portion in the width direction, and a third bridging portion provided on the downstream side in the discharge direction with respect to the second bridging portion and having a steeper inclination in the gravitational direction from the upstream side to the downstream side in the discharge direction than the second bridging portion.
[0012] According to this aspect, it has a second bridging portion and a third bridging portion provided on the downstream side in the discharge direction with respect to the second bridging portion and having a steeper inclination in the gravitational direction from the upstream side to the downstream side in the discharge direction than the second bridging portion. Therefore, the discharged medium can be firmly held by the second bridging portion on the upstream side in the discharge direction, and can be made into a wavy shape by the third bridging portion on the downstream side in the discharge direction. In particular, it is possible to effectively suppress the tip in the discharge direction from being caught on the hanging support surface, the placed medium, or the like.
[0013] In the medium placement device according to the fourth aspect of the present invention, in any one of the first to third aspects, the bridging member has a steep inclination portion at the upstream end portion in the discharge direction, and the inclination in the gravitational direction from the upstream side to the downstream side in the discharge direction is steeper than that in the region other than the upstream end portion in the discharge direction.
[0014] For example, depending on the type of medium, there is a medium whose tip is particularly likely to droop. However, according to this aspect, the bridging member has a steeply inclined portion at the upstream end in the discharge direction. Therefore, even when the tip of the medium droops, by bringing the tip into contact with the steeply inclined portion, the incident angle of the tip to the bridging member can be reduced, and the medium can be moved particularly efficiently.
[0015] In the medium placement device according to the fifth aspect of the present invention, in any one of the first to fourth aspects, the bridging member has a high-friction portion at the upstream end in the discharge direction, where the coefficient of static friction with respect to the medium is greater than that in a region other than the upstream end in the discharge direction.
[0016] According to this aspect, the bridging member has a high-friction portion at the upstream end in the discharge direction. Therefore, it is possible to suppress the placed medium on the medium placement device from sliding due to the influence of gravity and moving from the desired placement position, or being pushed by the medium that is later discharged from the discharge portion and moving, and the placed medium moving from the desired placement position.
[0017] In the medium placement device according to the sixth aspect of the present invention, in any one of the first to fifth aspects, the bridging member is configured to be disposed below the discharge portion in the direction of gravity by a thickness greater than or equal to the thickness of a plurality of the media.
[0018] When the bridging member is formed flush with the discharge portion, there is a risk that the placed medium will be pushed by the medium that is later discharged from the discharge portion and move from the desired placement position. However, according to this aspect, the bridging member is configured to be disposed below the discharge portion in the direction of gravity by a thickness greater than or equal to the thickness of a plurality of the media. Therefore, a plurality of media can be suitably placed.
[0019] In the medium placement device according to the seventh aspect of the present invention, in any one of the first to sixth aspects, the bridging member has a rotation axis and a predetermined or more loadThe device is characterized by rotating around the pivot axis relative to the first support when the force is applied.
[0020] According to this embodiment, the bridging member has a pivot axis and a predetermined or greater load When the force is applied, the first support part rotates relative to the first support part, which is rotatable relative to the first support part. For this reason, the bridging member has a predetermined or greater force. load This helps to prevent damage to the bridging members and support parts when such forces are applied.
[0021] In the eighth aspect of the present invention, the media mounting device is configured such that, in any one of the first to seventh aspects, the bridging member is detachably configured with respect to the first support portion, and a predetermined or greater load It is characterized by detaching from the first support portion when the force is applied.
[0022] According to this embodiment, the bridging member is configured to be removable from the first support portion, and is more than a predetermined amount load When this force is applied, it detaches from the first support. Therefore, the bridging member will not be subjected to a predetermined force or greater. load This helps to prevent damage to the bridging members and support parts when such forces are applied.
[0023] Hereinafter, an embodiment of the media loading device 100 according to the present invention will be specifically described with reference to the drawings. The media loading device 100 according to the present invention is a media loading device capable of loading multiple media 22 discharged from the discharge section 53 of a recording device 10, which is an example of a processing device. In this embodiment, the media loading device 100 can be connected to a recording device 10, which is an example of a processing device, but it may also be connected to a processing device other than a recording device, such as an image reading device. First, an overview of the recording device 10 will be described with reference to Figure 1.
[0024] The coordinates indicated in the drawings assume that the recording device 10 is placed on a horizontal surface, and the three mutually orthogonal virtual axes are defined as the X-axis, Y-axis, and Z-axis. The X-axis is a virtual axis parallel to the left-right direction (width direction) of the recording device 10. The Y-axis is a virtual axis parallel to the front-back direction of the recording device 10. The Z-axis is a virtual axis parallel to the height direction (gravity direction) of the recording device 10. The tip of the arrows representing the X-axis, Y-axis, and Z-axis is designated as the "+ side," and the base end is designated as the "- side." The recording device 10 illustrated in this embodiment is a large-format printer that records using an inkjet method by unwinding a long, rolled medium 22. The recording device 10 in this embodiment is a printer capable of recording on medium 22 up to a maximum size of B0+.
[0025] As shown in Figure 1, the recording device 10 is installed via casters 11. The recording device 10 has a roughly rectangular prism-shaped housing 12 that is long in the X direction. The housing 12 has a front wall 13, a rear wall 14, a first side wall 15, a second side wall 16, and a top wall 17. In the recording device 10, the direction in which the base frame 65 and the top wall 17 face each other is the height direction of the recording device 10. The direction in which the first side wall 15 and the second side wall 16 face each other is the left-right direction of the recording device 10. The direction in which the front wall 13 and the rear wall 14 face each other is the front-rear direction of the recording device 10.
[0026] Inside the housing 12 are a recording unit 30 having a recording head 34 for recording onto the medium 22, and a storage unit 20 for housing a roll body 25 in which the medium 22 is wound in a cylindrical shape. Although not shown in Figure 1, there are also a transport unit for transporting the medium 22 and a cutting unit for cutting the medium 22.
[0027] Multiple openings are formed in the front wall 13 of the housing 12. A roll body storage opening 27 for accommodating the roll body 25 is formed on the base frame 65 side below the front wall 13. In addition, an ejection section 53 for ejecting the recorded medium 22 is formed above the roll body storage opening 27.
[0028] The housing section 20 houses a cylindrical roll body 25 formed by winding a long medium 22 around a core member 23, which is detachably housed through a roll body housing opening 27. In this embodiment, the housing section 20 is configured to house two roll bodies 25 that are long in the X direction, arranged side by side in the Z direction. A pair of holding members 28 are attached to both ends of the roll body 25 to rotatably hold it relative to the housing section 20. When the roll body 25 is rotated, the medium 22 wound around the roll body 25 is sent towards the rear wall 14 side of the housing 12. The medium 22 is then transported to a support base 31 by a transport unit (not shown), and the medium 22 is transported on the support base 31 from the rear wall 14 side to the front wall 13 side.
[0029] The recording unit 30 comprises a support base 31, a guide member 32, a carriage 33, and a recording head 34. The support base 31 is a plate-shaped member extending in the X direction within the housing 12, located on the upper wall 17 side of the housing unit 20, and supports the medium 22 transported by a transport unit (not shown).
[0030] The recording head 34 is mounted on a carriage 33 that moves along a guide member 32. The recording head 34 is located on the support base 31 side relative to the carriage 33. The recording head 34 is configured to reciprocate along the guide member 32 together with the carriage 33. The recording head 34 is connected to an ink cartridge 35 by a flexible tube (not shown). The recording head 34 records onto the medium 22 supported by the support base 31 by ejecting ink while moving in the X direction. The recorded medium 22 is cut by a cutting section (not shown).
[0031] Furthermore, the recording device 10 has an input unit 59. The input unit 59 is provided on the upper surface of the upper wall 17 of the housing 12. The input unit 59 is composed of, for example, a liquid crystal display device with a touch panel, and is used when the user inputs various types of information.
[0032] [Example 1] The media mounting device 100 of Embodiment 1 of the present invention will be described in detail below with reference to Figures 2 to 9. The media mounting device 100 of this embodiment is connectable to a recording device 10, as shown in Figures 2 and 8, and is configured to allow multiple media 22 discharged from the discharge section 53 of the recording device 10 in the discharge direction A to be stacked on the support surface 111 of the support section 110.
[0033] As shown in Figures 4 and 6, the media placement device 100 of this embodiment supports the media 22 discharged from the discharge section 53 from below in the direction of gravity (Z direction) with a support surface 111, by a plurality of support sections 110 provided in the width direction (X direction) intersecting the discharge direction A of the media 22. In the media placement device 100 of this embodiment, the plurality of support sections are arranged such that the central positions in the width direction of adjacent support sections 110 are spaced 160 mm apart. Here, as shown in Figures 3 and 4, the support sections 110 extend in the discharge direction A and are inclined to become lower in the direction of gravity from the upstream side to the downstream side of the discharge direction A. Furthermore, as the support sections 110, there are alternating first support sections 110a and second support sections 110b, which are positioned lower in the Z direction than the first support section 110a when viewed from the X direction as shown in Figure 3, as shown in Figure 5 and 6, in the X direction.
[0034] As described above, in the media loading device 100 of this embodiment, the support portion 110 extends in the discharge direction A and is inclined to become lower in the direction of gravity from the upstream side to the downstream side in the discharge direction A. Therefore, the media 22 can be moved using gravity, and the media 22 can be moved efficiently without using power or other means. Furthermore, since the support portion 110 has first support portion 110a and second support portion 110b alternately in the width direction, the media 22 moving when viewed from the discharge direction A can be made into a wavy shape (cockling shape), and the tip in the discharge direction A will not droop down and get caught on the support surface 111 or media already loaded on the support surface 111. Therefore, the media loading device 100 of this embodiment can suitably load various types of media 22 without using power or other means. In the media loading device 100 of this embodiment, as shown in Figure 5, the heights of the first support portions 110a and the heights of the second support portions 110b are generally uniform. However, the configuration is not limited to this, and the heights of the first support parts 110a and the second support parts 110b may be different. Also, in the media placement device 100 of this embodiment, the height difference between the first support part 110a and the second support part 110b is 45 mm. However, it does not have to be 45 mm as long as a height difference that can be secured to give the media 22 a wavy shape can be secured.
[0035] Furthermore, as shown in Figures 3, 4, and 6, the media placement device 100 of this embodiment has, as each support section 110, an upstream section 110A located upstream of the discharge direction A, a downstream section 110B located downstream of the upstream section 110A in the discharge direction A, and a midstream section 110D connecting the upstream section 110A and the downstream section 110B. In addition, a bridging member 110C is provided further upstream of the upstream section 110A in the discharge direction A, connecting the lower side of the discharge section 53 of the recording device 10 with the upstream section 110A. In detail, the bridging member 110C is provided on the first support section 110a and is configured to bridge the lower side of the discharge section 53 in the direction of gravity with the support surface 111 of the first support section 110a. The bridging member 110C can be considered as constituting a part of the support section 110, or it can be considered as a separate member that can be attached to the support section 110.
[0036] As described above, the media loading device 100 of this embodiment is provided with a bridging member 110C on the first support portion 110a that bridges the lower side of the discharge portion 53 in the direction of gravity and the support surface 111 of the first support portion 110a. Therefore, the media loading device 100 of this embodiment can prevent the leading edge of the discharged media 22 from hanging down between the discharge portion 52 and the support surface 111 of the first support portion 110a, preventing the discharged media 22 from reaching the support surface 111 of the first support portion 110a, and can also prevent the leading edge of the media 22 from getting caught in the discharge path between the discharge portion 53 and the first support portion 110a. Thus, the media loading device 100 of this embodiment can suitably load the media 22 discharged from the processing device.
[0037] In this embodiment, the media placement device 100 is configured such that the bridging member 110C is provided only on the first support portion 110a and not on the second support portion 110b, but the device is not limited to this configuration. As an example of a configuration in which the bridging member 110C is provided on the first support portion 110a, the bridging member 110C may also be provided on the second support portion 110b in addition to the first support portion 110a. However, in this case, it is preferable that the bridging member 110C provided on the second support portion 110b is positioned lower in the direction of gravity when viewed from the X direction than the bridging member 110C provided on the first support portion 110a. This is because the media 22 moving when viewed from the discharge direction A can be made into a wavy shape, and the leading edge of the media 22 moving on the bridging member 110C can be prevented from drooping.
[0038] Furthermore, in this embodiment, the first support portion 110a and the bridging member 110C are configured to be in a continuous straight line when viewed from the X direction, and the inclination of the first support portion 110a and the bridging member 110C is the same. However, the configuration is not limited to this. The inclination of the bridging member 110C can be appropriately determined according to the distance between the processing device such as the recording device 10 and the media placement device 100, the position of the discharge portion 53, etc.
[0039] As shown in Figure 3, the middle section 110D is steeper in slope than the upstream section 110A and the downstream section 110B when viewed from the X direction. For example, when using a large medium 22 such as B0 Nobi size, jams of the medium 22 discharged in the middle section 110D are particularly likely to occur. For this reason, a configuration that allows for easy movement of the medium 22 in the middle section 110D is preferable. In this embodiment, the medium loading device 100 has an upstream section 110A, a downstream section 110B, and a middle section 110D, and the middle section 110D is steeper in slope than the upstream and downstream sections when viewed from the X direction. By making the middle section 110D steeper in slope, the medium 22 can be moved particularly efficiently using gravity in the middle section 110D. Therefore, the medium loading device 100 of this embodiment can load various types of medium 22 particularly suitably without using power or the like.
[0040] In this embodiment, the middle section 110D has a steeper slope than the upstream section 110A and the downstream section 110B, and the upstream section 110A has a steeper slope than the downstream section 110B. However, the configuration is not limited to this, and for example, the upstream section 110A and the downstream section 110B may have the same slope. Also, in this embodiment, the position of the middle section 110D in the discharge direction A is near the center of the total length of the support section 110 in the discharge direction A. In other words, this position corresponds to the vicinity of the center in the discharge direction A of the medium 22 of B0 Nobi size, which is the maximum size that can be loaded by the medium loading device 100 of this embodiment. However, there are no particular limitations on the position or length of the middle section 110D in the discharge direction A, and the position and length of the middle section 110D in the discharge direction can be appropriately determined according to the type and size of the medium 22 used.
[0041] Furthermore, as shown in Figures 4 and 6, the media mounting device 100 of this embodiment is configured such that a space S is provided between the first support portion 110a and the second support portion 110b in the X direction, and the width of the space S in the X direction is wider than the width of the support surface 111 in the X direction. In other words, in the media mounting device 100 of this embodiment, the contact area between the support surface 111 and the media 22 is reduced. As a result, the frictional force between the support surface 111 and the media 22 can be reduced, and various types of media 22 can be loaded particularly suitably without using power or the like. In addition, since the support portion 110 can be made lightweight, the media mounting device 100 can also be made lighter.
[0042] Furthermore, as shown in Figures 2 to 5, the media placement device 100 of this embodiment includes a pressing part 120 that presses down on the media 22 supported by the support part 110 from above in the Z direction. As shown in Figure 5, the pressing part 120 is positioned opposite the support surface 111 of the first support part 110a. With this configuration, the media placement device 100 of this embodiment can sandwich the media 22 from above and below between the pressing part 120 and the support surface 111 of the first support part 110a, effectively preventing the media 22 from curling when viewed from the X direction and the leading edge of the media 22 from getting caught on the support surface 111 or other placed media.
[0043] Furthermore, as shown in Figures 2 to 5, the media placement device 100 of this embodiment is equipped with a restricting section 121 that restricts the movement of the media 22 supported by the support section 110 to the downstream side in the discharge direction A by a restricting surface 121A extending from the support surface 111 side (-Z direction side) to the pressing section 120 side (+Z direction side). Therefore, when placing media 22 on the support section 110 continuously, the leading edge of the media 22 that has moved to be placed will come into contact with and get caught on the media that has already been placed on the lower side, which can effectively prevent the newly moved media 22 from being poorly discharged, and also prevent the already placed media from being pushed out of the support section 110.
[0044] As shown in Figures 4 and 5, the media mounting device 100 of this embodiment has the regulating unit 121 located on the -X side in the X direction. This is because the recording device 10 used with the media mounting device 100 of this embodiment has the carriage 33's home position on the -X side, and uses the media 22 positioned towards the -X side. Therefore, the media mounting device 100 is not limited to this configuration and can be arbitrarily arranged depending on the configuration of the processing device used with it.
[0045] Furthermore, as shown in Figures 4 and 7, the media loading device 100 of this embodiment includes a restricting part holding shaft 122 provided along the discharge direction A. The restricting part 121 is movable along the restricting part holding shaft 122. Thus, the restricting part 121 is movable along the discharge direction A. Therefore, the media loading device 100 of this embodiment can suitably change the position of the restricting part 121 according to the size of the media 22 used, and can suitably load the media 22.
[0046] Furthermore, the pressing portion 120 in the media placement device 100 of this embodiment, as shown in Figures 2 to 4, has an upstream pressing portion 120A and a downstream pressing portion 120B positioned downstream of the upstream pressing portion 120A in the discharge direction A and including the center in the X direction. Therefore, when using a short medium 22, only the upstream pressing portion 120A of the media placement device 100 of this embodiment is used, and when using a long medium 22, both the upstream pressing portion 120A and the downstream pressing portion 120B can be used. Thus, the media placement device 100 of this embodiment can effectively clamp the medium 22 from above and below between the pressing portion 120 and the support surface 111, not only when using a short medium 22 but also when using a long medium 22. The downstream pressing portion 120B can be rotated and folded when using a short medium 22, and both states are shown in Figures 3 and 4 to show the state in use and the state when folded when not in use.
[0047] Here, as shown in Figures 3 and 8, the upstream retaining portion 120A has a base portion 1210 extending in the discharge direction A, and a plurality of arm portions 1220 provided on the base portion 1210 at a position facing the support surface 111. The base end 1221 of the arm portion 1220 is rotatably attached to the base portion 1210 with the X direction as the axis of rotation, and a rotating member 1223 is provided at the tip 1222 opposite to the base end 1221, which is rotatable with the X direction as the axis of rotation. On the other hand, as shown in Figure 7, the downstream retaining portion 120B extends in the discharge direction A and has a plurality of rotating bodies 1230 provided at a position facing the support surface 111, which are rotatable with the X direction as the axis of rotation. And, as shown in Figure 7, the distance G1 between the downstream retaining portion 120B and the support surface 111 is configured to be narrower than the distance G2 between the base portion 1210 and the support surface 111.
[0048] Generally, when using short media 22, the number of media 22 sheets that can be stacked is greater than when using long media 22. This is because, for example, the recording device 10 shown in Figure 1, which can be used with the media stacking device 100 of this embodiment, can set two rolls of roll body 25, but the number of media 22 sheets that can be stacked increases when the roll body 25 is cut short, and decreases when the roll body 25 is cut long. In the media stacking device 100 of this embodiment, the distance G1 between the downstream pressing part 120B and the support surface 111 is narrower than the distance G2 between the base part 1210 and the support surface 111, so it is possible to stack more media 22 sheets when using short media 22 than when using long media 22. Furthermore, the upstream pressing portion 120A has a base portion 1210 and a plurality of arm portions 1220, and the base end 1221 of the arm portion 1220 is rotatable relative to the base portion 1210 with the width direction as the pivot axis, and a rotating member 1223 is provided at the tip 1222 of the arm portion 1220. This configuration allows the medium 22 to be firmly held on the upstream side in the discharge direction A, and the medium 22 to be moved appropriately. In addition, the rotating member 1223 and the rotating body 1230 are provided to facilitate the movement of the medium 22.
[0049] Furthermore, as shown in Figures 2 and 7, the media placement device 100 of this embodiment is equipped with casters 123 on the lower side in the direction of gravity at the downstream end 124 in the discharge direction A. Therefore, the media placement device 100 can be stably installed by placing the casters 123 on the installation surface, and the media placement device 100 can be easily moved.
[0050] Furthermore, as shown in Figure 8, in the media placement device 100 of this embodiment, the media 22 is discharged from a pair of rollers provided in the discharge section 53, but the position of the pair of rollers in the discharge section 53 is raised by a predetermined height relative to the support surface 111 of the bridging member 110C. In other words, the bridging member 110C is configured to be positioned below the discharge section 53 in the direction of gravity by a thickness of multiple media 22 or more. If the bridging member 110C is formed flush with the discharge section 53, there is a risk that the placed media will be pushed away from the desired placement position by the media 22 that is later discharged from the discharge section 53 and moves. However, in the media placement device 100 of this embodiment, the bridging member 110C is configured to be positioned below the discharge section 53 in the direction of gravity by a thickness of multiple media 22 or more. For this reason, the media placement device 100 of this embodiment can suitably place multiple media 22.
[0051] Furthermore, as shown in Figure 9, the bridging member 110C has a pivot shaft 112 that is rotatable relative to the first support portion 110a, and moves in the Z direction beyond a predetermined distance. load When this force is applied, the first support portion 110a rotates in the rotational direction R. Therefore, in this embodiment, the media placement device 100 has the bridging member 110C rotated in the Z direction beyond a predetermined amount. load The configuration is designed to prevent damage to the bridging member 110C and other parts of the support section 110 when the force is applied.
[0052] Furthermore, the bridging member 110C is configured to be removable from the first support portion 110a, and extends beyond a predetermined distance in the X direction. loadWhen pressure is applied, it detaches from the first support portion 110a without deformation. For this reason, the media mounting device 100 of this embodiment has a predetermined or greater pressure in the X direction on the bridging member 110C. load The configuration is designed to prevent damage to the bridging member 110C and other parts of the support part 110 when the force is applied.
[0053] [Example 2] Next, the media mounting device 100 of Example 2 will be described using Figure 10. Figure 10 corresponds to Figure 9 in the media mounting device 100 of Example 1. In Figure 10, components common to Example 1 are indicated by the same reference numerals, and detailed explanations will be omitted. Here, the media mounting device 100 of this example has the same configuration as the media mounting device 100 of Example 1, except for the configuration of the bridging member 110C. Therefore, with respect to parts other than those described below, the media mounting device 100 of this example has the same characteristics as the media mounting device 100 of Example 1.
[0054] As shown in Figure 10, the media placement device 100 of this embodiment is provided with a steeply inclined portion 113 at the upstream end of the bridging member 110C in the discharge direction A, which has a steep slope 113A that is steeper than the rest of the support surface 111 of the bridging member 110C when viewed from the X direction. In other words, the bridging member 110C of this embodiment has a steeply inclined portion 113 at the upstream end in the discharge direction A, which has a steeper slope in the direction of gravity from the upstream to the downstream side of the discharge direction A than the rest of the area in the discharge direction A. For example, depending on the type of media 22, the tip of the media 22 may be particularly prone to sagging. However, the bridging member 110C of this embodiment has a steeply inclined portion 113 at the upstream end in the discharge direction A. Therefore, even if the tip of the medium 22 droops, by making the tip contact the steeply inclined portion 113, the angle of incidence of the tip to the bridging member 110C can be reduced, and the medium 22 can be moved particularly efficiently.
[0055] [Example 3] Next, the media mounting device 100 of Example 3 will be described using Figure 11. Figure 11 corresponds to Figure 9 in the media mounting device 100 of Example 1. In Figure 11, components common to both Example 1 and Example 2 are indicated by the same reference numerals, and detailed explanations will be omitted. Here, the media mounting device 100 of this example has the same configuration as the media mounting devices 100 of Example 1 and Example 2, except for the configuration of the bridging member 110C. Therefore, with respect to parts other than those described below, the media mounting device 100 of this example has the same characteristics as the media mounting devices 100 of Example 1 and Example 2.
[0056] As shown in Figure 11, the media placement device 100 of this embodiment is equipped with a high-friction portion 114 at the upstream end of the bridging member 110C in the discharge direction A. More specifically, the bridging member 110C of this embodiment has a high-friction portion 114 at the upstream end in the discharge direction A, which has a higher static friction coefficient with respect to the media 22 than the area other than the upstream end in the discharge direction A. Therefore, the media placement device 100 of this embodiment can prevent the placed media placed on the media placement device 100 from sliding due to gravity and moving from the desired placement position, and also prevents the placed media from moving from the desired placement position due to being pushed by the media 22 that is later discharged from the discharge section 53.
[0057] [Example 4] Next, the media mounting device 100 of Example 4 will be described using Figure 12. Figure 12 corresponds to Figure 9 in the media mounting device 100 of Example 1. In Figure 12, components common to Examples 1 to 3 are indicated by the same reference numerals, and detailed explanations will be omitted. Here, the media mounting device 100 of this example has the same configuration as the media mounting devices 100 of Examples 1 to 3, except for the configuration of the bridging member 110C. Therefore, with respect to parts other than those described below, the media mounting device 100 of this example has the same characteristics as the media mounting devices 100 of Examples 1 to 3.
[0058] As shown in Figure 12, the media placement device 100 of this embodiment is equipped with a steeply inclined section 113 having a steep slope 113A at the upstream end of the bridging member 110C in the discharge direction A, as in the media placement device 100 of Embodiment 2, and is equipped with a high-friction section 114 at the upstream end of the bridging member 110C in the discharge direction A, as in the media placement device 100 of Embodiment 3. Therefore, the media 22 can be moved particularly efficiently, and the movement of the placed media from the desired placement position can be suppressed.
[0059] [Example 5] Next, the media mounting device 100 of Example 5 will be described using Figures 13 to 15. In Figures 13 to 15, components common to Examples 1 to 4 are indicated by the same reference numerals, and detailed explanations will be omitted. Here, the media mounting device 100 of this example has the same configuration as the media mounting devices 100 of Examples 1 to 4, except for the configuration of the bridging member 110C. Therefore, with respect to parts other than those described below, the media mounting device 100 of this example has the same characteristics as the media mounting devices 100 of Examples 1 to 4.
[0060] As shown in Figure 13, the bridging member 110C of this embodiment has a first bridging portion 1101 extending from the first support portion 110a in the discharge direction A, a second bridging portion 1102 provided on both sides of the first support portion in the X direction, and a third bridging portion 1103 provided downstream of the second bridging portion 1102 in the discharge direction A, and having a steeper slope in the direction of gravity from upstream to downstream of the second bridging portion 1102 in the discharge direction A. With this configuration, as shown in Figure 15, the media placement device 100 of this embodiment can firmly hold the discharged media 22 at the second bridging portion 1102 on the upstream side of the discharge direction A, and create a wavy shape at the third bridging portion 1103 on the downstream side of the discharge direction A, which is particularly effective in preventing the tip in the discharge direction A from drooping and getting caught on the support surface 111 or the placed media.
[0061] Here, the downstream end of the third bridging section 1103 in the discharge direction A extends to a position lower than the height of the second support section 110b. With this configuration, the wavy-shaped medium 22 can be reliably fed to the second support section 110b. In this embodiment, the width L1 of the first support section 110a of each bridging member 110C shown in Figure 15 is 23 mm. Also, the width L2 of the second support section 110b of each bridging member 110C shown in Figure 15 is 257 mm, the distance G3 between adjacent second bridging sections 1102 shown in Figure 13 is 65 mm, and the length L3 of the second support section 110b in the discharge direction A shown in Figure 14 is 115 mm. Furthermore, the length L4 of the third bridging portion 1103 of each bridging member 110C shown in Figure 14 in the discharge direction A is 159 mm, and the angle Θ in the +Z direction between the second bridging portion 1102 and the third bridging portion 1103 shown in Figure 14 is 18°. However, the configuration is not limited to this.
